Current code does not update current firmware version in the FWST table. Read current version and update it in the Fwst ACPI table.

Boot process halts on STAGE_2.

Debug log as below:
...
ACPI Ret: Success

STAGE_2: System halted!

I attached the complete log file just in case.

And, on a side note, I reverted to the version before PR #198 and there wasn't an issue.

When trying to enable USB keyboard console for QEMU with Slim Bootloader, sometimes it works. But it is not reliable, and lots of error message will be printed on console in QEMU.
For example:
XhcPeiCheckUrbResult: Transfer Default Error Occur! Completecode = 0x13!
XhcPeiSetTrDequeuePointer: Set TR Dequeue Pointer Failed, Status = Device Error
XhcPeiDequeueTrbFromEndpoint: Set Dequeue Pointer Failed, Status = Device Error
XhcPeiBulkTransfer: XhcPeiDequeueTrbFromEndpoint failed

and SlimBootloaderIntegration.txt in (https://github.com/tianocore/edk2-staging/tree/UEFIPayload).

'MinnowBoard3' and 'Qemu' is supported.
Does Apollo Lake also support integration and how to integrate it?

Putting iasimage.bin1234 at the root of the FAT file system, SBL OsLoader can still load it in the same way as iasimage.bin. It is expected to be failed due to mismatching file name.

When FwuImage.bin does not exist, the FWU flow will cause assertion.

Below is the log:

A device entry for INT34D2 is missing under Platform/ApollolakeBoardPkg/AcpiTables/Dsdt/Platform.asl. The ACPI entry is necessary for the intel_pmc_ipc driver to load up automatically on Linux.

NHLT table is not integrated in ACPI table by SBL. NHLT table has audio device specific informatinon, which is needed for audio device to work on APL-UP2.
Could SBL intergrate NHLT table on APL-UP2 to support audio?

On WHL with Boot Guard profile 0, if booting from SBL boot partition 1, the boot time is significantly longer than booting from boot partition 0.

Following instructions at https://slimbootloader.github.io/how-tos/boot-acrn.html,
latest SBL could not boot to ACRN. Instead, it fell back to fast boot always.

The FirmwareDevice class method ParseFsp(self) (IntelFsp2Pkg/Tools/SplitFspBin.py), called when building slim bootloader for Qemu fails to parse the built QemuFsp Fd file correctly.

The Fd (built using "python BuildLoader.py build qemu") correctly contains 3 EFI Fvs, one each to eventually be "split" into FSP_S.bin, FSP_M.bin, and FSP_T.bin. The FSP Information Headers all appear to be in the correct places within the Fd (e.g. Silicon/QemuSocPkg/FspBin/FspRel.bin) "equivalent to" each EFI Fv (S at 0x00, M at 0x15000, T at 0x37000).

Subsequent processing by postbuild in BuildLoader.py expects those 3 FSPImage files, however there are only 2 FSPImage files created by the split, with the M FSPImage improperly containing the T Fv in addition to its' M Fv.

The first indication of trouble is an alignment warning from the BPDG tool:

`VPD input data file: = Build/QemuFspPkg/RELEASE_GCC5/FV/34686CA3-34F9-4901-B82A-BA630F0714C6.txt

• Vpd pcd fixed done! -`

I am not sure if I need to investigate this warning "upstream" or if the BPDG tool was trying to tell me it "fixed" the alignment problem with the upstream inputs and it is OK to move forward.

For fast boot, after 119 boots, the memory training process repeats. This causes an unacceptably long boot time.

StitchIfwi '-q' argument does not take effect. SPI QAUD mode should be enabled with '-q'. But the actually stitched image still uses SPI SINGLE mode.

SBL QEMU does not compile when set EXECUTE_IN_PLACE=1 in BoardConfig.py.

With latest code, firmware update flow gets into infinite loop on APL platform.

Dear Slim boot loader team,

There is a compile issue when use Visual studio 2015, I tried to bring up an Apollo lake platform.

• Silicon\ApollolakePkg\Include\Library/HeciLib.h: warning C4819: The file contains a character that cannot be represented in the current code page (950). Save the file in Unicode format to prevent data loss

I found the root-cause in the HeciLib.h. (the change patch is in the attachment)

Per design, SBL allows to set PLT_SOURCE environment variable to search supported boards and silicons from different location. When we tried this way, the build failed because the FSP and Microcode downloading still points to the boards and silicon inside SBL rather than the new location.

Hi,

I am interested in bootloader for ARM Cortex-M architecture. Are there plans to support it?

When SBL calls board notification ReadyToBoot and EndOfFirmware in Stage2, OsLoader will assert on APL platform.
Debug log as below:
...
Payload normal heap: 0x4000000 (0xE3A000 used)
Payload reserved heap: 0x900000 (0x0 used)
Payload stack: 0x10000 (0x1C00 used)

ASSERT [Stage2] w:\slimboot\slimfork\MdePkg\Library\BaseMemoryLibSse2\ZeroMemWrapper.c(47): Buffer != ((void *) 0)

STAGE_2: System halted!

On APL some of ACPI FADT parameter does not match SOC. For example, GPE0 block length should be 32 bytes rather than 16 bytes.

SBL initializes APL GFX OpRegion structure during boot. However, due to improper code execution order, the ACPI GNVS ASLB field was zeroed out during the GNVS initialization.

When USB key board is enabled as console input, booting UP2 is halted if a user presses keyboard before USB keyboard is initialized. The assert message is the following:

====================Os Loader====================

ASSERT [OsLoader] 
.../BootloaderCommonPkg/Library/XhciLib/XhciSched.c(2739): Index != TrsRing->TrbNumber

STAGE_PAYLOAD: System halted!  

Pressing keyboard after USB keyboard is initialized (typically as soon as logo is shown) works as expect - which enters SBL shell.

Windows 10 installation will hard hang on Leafhill with UEFI payload.

TE image base is not calculated properly in PeCoffGetPreferredBase().
TE image has stripped header. When calculating the preferred base for TE image, the gap should be added back to match the actual TE image base.

When trying to patch CFGDATA using CfgDataTool on WHL, it failed with message below:
C:\Python27\python.exe W:\SlimBoot\SlimFork\BootloaderCorePkg\Tools\CfgDataTool.py replace -i d:\upx.bin d:\CfgData.bin -o d:\upx.bin
No CFGDATA region has been patched!

Open WHL/CFL CfgDataDef.dsc and click memory settings, then it shows WARNING.

WARNING: Value "8388608" is an invalid option for "TsegSize" !
Update TsegSize from 0x00800000 to 0x01000000 !

Using latest code, when booting from 2nd boot option on APL, the following assertion was seen:

ASSERT [OsLoader] w:\slimboot\slimfork\MdePkg\Library\BaseLib\LinkedList.c(267): InternalBaseLibIsListValid (ListHead)

Stitching an IAS image of ~32MB including kernel and initrd, SBL failed to load it with hash verification errors. Smaller IAS image (~16MB) is just fine.

Issue:
The Bios.xml generated from StitchIfwi.py is referring to Stitch_PROV.bin.
But the SBL Output Stitch_Components.zip contain instead Stitch_FB.bin.

The topic has been already discussed with @mauricema in May.

We have recently introduced Device Table concept for the OS Boot media devices. Code changes are needed in QEMU and APL in order to match this new concept.

Run "python PatchFv.py" will display:

Hello,

At this moment it is important to have identical configuration between SBL and UEFI Payload for the PCIe base. As SBL knows the PCIe base why not add this to the information that is passed between SBL and UEFI Payload. There hardly isn't an effort involved and it prevent configuration issues.

Regards,
Wim

To reproduce it on APL, just enable USB KB by changing following in BoardConfig.py
self.CONSOLE_IN_DEVICE_MASK = 0x00000003

After it is done, if USB is not the 1st boot option, an assertion will be seen.

I'm trying to write (note: since i don’t have a devboard yet, i test it in QEMU) an UEFI driver that writes/reads values in NVRAM storage, but got a problem:

Variable driver will work at emulated non-volatile variable mode!

Apparently, NVRAM is emulated by UEFI payload in RAM - and it seems to be cleaned after UEFI starts OS bootloader. Is this a QEMU-specific problem or Slimbootloader doesn't support a NVRAM storage on SPI flash/img file?

During Linux kernel boot, the following message will be printed out:
[Firmware Info]: PCI: MMCONFIG at [mem 0xe0000000-0xefffffff] not reserved in ACPI motherboard resources
PCI: not using MMCONFIG
This prevents kernel from using MMCONFIG for PCI access.

SBL suggests to use VS2015. But when there are multi versions of VS (including VS2015) installed on the Windows host system, BuildLoader.py often sets up old VS version for the toolchain variable which might cause build errors all the time.

During development, we found the build did not throw error when duplicated names exist in the CFGDATA database. It makes it difficult to debug later on. We should let the build script check this and report error.

Even after SBL initialized framebuffer correctly, the Linux kernel still failed to show console on fbdev. The screen is blank.

The build process (via BuildLoader.py) will spawn subprocesses to sign and assemble files. To determine the location of rsa and nasm, BuildLoader.py will search for OPENSSL_PATH and NASM_PREFIX environment variables, respectively. If not set, BuildLoader.py will initialize these environment variabels with assumed default locations. However, if openssl or nasm executables cannot be found, an exception will be generated when trying to spawn the associated subprocess, a traceback will be printed, and the build will halt.

Example traceback from Python when openssl cannot be found:

These tracebacks can be confusing for people who are trying to download and build the code base without following the instructions provided in the documentation. Instead, Slim Bootloader should search for the associated executables and report a friendlier error message if they cannot be found possibly instructing the user to install the required tool.

Fail to change the delta configuration file using the ConfigEditor.

Steps:

1. Start ConfigEditor.
2. Load Config DSC file: Platform/ApollolakeBoardPkg/CfgData/CfgDataDef.dsc
3. Load Config Changes from Delta file: Platform/ApollolakeBoardPkg/CfgData/CfgData_Ext_Gpmrb.dlt
4. Change values in OS Boot Options.

When there is no USB boot option in boot option list, and console input device is using USB keyboard, the keyboard does not get initialized thus does not work.
